Wohler Technologies Inc. has released the AMP2-16-3G audio monitor, a 3Gbps-capable 16-channel monitor introduced to address broadcasters' migration to HD and their increasing reliance on higher-capacity 3Gbps video transport infrastructures.

The monitor leverages the unique flexibility of the popular WohlerPlus audio processing platform to ensure versatile, future-proof functionality with 3Gbps support. Wohler's AMP2-16-3G provides simultaneous display for up to 16 channels of embedded audio within a single multirate 3Gbps signal. Equipped with five card slots, the audio monitor allows users to "pick and mix" their inputs and adapt the AMP2-16-3G to the evolving needs of the broadcast operation. This same functionality also enables users of Wohler's AMP2-16MSDI system, available with Audio Engineering Society (AES) and Dolby® E options, to upgrade their systems with the addition of a 3Gbps card. In addition to providing flexible input support, the AMP2-16-3G audio monitor addresses key issues in DTV audio delivery, providing measurement of program loudness in adherence with ITU-1770/1771, which is displayed prominently on the unit's LCD status screen. The monitor includes demuxed outputs of eight AES pairs on BNC connectors and also provides a reclocked loop output of the 3Gbps signal. The monitor's high-resolution LCD display boasts colorful 210-segment high-resolution bar graph level meters. Colors and settings for scale and range are user-selectable along with several predefined scales and ballistics including AES, BBC, and Nordic. Each displayed meter set clearly indicates the phase for stereo sources prior to output on the speakers.
